Alpinestars SMX Plus Motorcycle Boots - Black/White/Red Fluorescent, US 9 / EU 43 - Model 2221019-1231-43

The Alpinestars SMX Plus Boots are engineered to deliver high-performance protection combined with exceptional comfort for motorcycle riders. Crafted with an advanced microfiber upper, these boots offer a lightweight design that enhances mobility while maintaining durability. The front flex zone, constructed with soft microfiber, improves abrasion resistance and allows for natural forward and backward movement, making them suitable for aggressive riding styles. An accordion microfiber panel over the Achilles area provides flexible movement and added comfort, while the stretchable accordion panel on the outside entry/exit ensures a snug fit and easy donning and removal.

A key feature of the SMX Plus boots is the evolution of Alpinestars' Multi-Link Control system, which offers external protection and support for ankle articulation. This system effectively limits hyper-torsion, hyper-extension, and hyper-flexion, providing comprehensive ankle stability. Protective elements include a replaceable dual-density TPU toe slider with a screw-in assembly, offering durability around the outer toe, and replaceable heel sliders designed to absorb shock and facilitate sliding during falls. Large, asymmetrical accordion zones on the front and rear increase flexibility and comfort, supporting long rides and dynamic movements.

Additional features include a micro-adjustable ratchet top closure with a stowable tab end for a secure fit, a laminated synthetic forefoot lining combined with open-cell foam for shock absorption, and a highly breathable lining around the ankle and leg for enhanced comfort. The anatomically designed, replaceable EVA footbed provides arch support and a firm pedal feel. The durable rubber sole offers consistent grip, optimized for riding feel, while the inner instep speed lacing closure and lateral zipper ensure a precise, secure fit. The Lace-Lock System, made from advanced polymer resin, allows quick and secure fastening, and hook-and-loop tabs keep the zipper pull in place. The contoured high-modulus shin plate adds superior impact and abrasion resistance, making these boots a top choice for riders seeking protection, comfort, and performance.
